According to the calling that includes the address from central means 200, whether signal processing circuit 62 is judged from the address of central means 200 outputs consistent with each address that is set in address setting element 65.When the address of exporting from central means 200 is consistent with each address that is set in address setting element 65, signal processing circuit 62 sends to central means 200 to detecting element 61 detected light detecting signals, perhaps controls according to the control signal of sending from central means 200.
For example, when each address of fire detector 10 was called out by central means 200, Signal Processing Element 62 made that by light source control element 66 LED 35 and 35 is luminous.In addition, when the amount that instruction is changed the light that sends from LED35 and 35 or when stopping luminous signal and being input into signal processing circuit 62, signal processing circuit 62 is to LED control signal corresponding with this signal of light source control element 66 outputs.
Light source control element 66 is circuit of directly controlling LED 35 and 35.According to the signal from signal processing circuit 62 outputs, light source control element 66 makes LED 35 and 35 launch the light of scheduled volume off and on usually, so-called current-carrying indication that Here it is.When the LED control signal was input into light source control element 66, light source control element 66 changed the amount of the light that sends from LED 35 and 35 or stops luminous.
Memory element 64 be one in order to the storage when Signal Processing Element 62 carries out various processing necessary memory of data.
As mentioned above, the LED 35 of fire detector 10 and 35 luminance are by central means 200 controls.The control of the luminance of LED 35 and 35 will be described below.
First kind of control method is to stop the current-carrying indication by setting.In this case, central means 200 is fulfiled the function of address that is provided with and registers that fire detector that need stop its current-carrying indication and the execution time that stops the current-carrying indication.
For example, the fire detector with particular address is provided with, so that stop the current-carrying indication from certain schedule time (it is the start time) in certain schedule time (it is a stand-by time) to morning at night.
In stand-by time, when central device 200 was called out the specific fire detector 10 that has been provided with and has registered, central means 200 sent a control signal that stops its current-carrying indication to fire detector 10.
When fire detector 10 received control signal, fire detector 10 memories are 64 li of memory elements, and were not luminous from LED 35 and 35 when being called out by central means 200 with convenient fire detector 10.From this time, when central device 200 was called out fire detector 10, fire detector did not carry out the current-carrying indication.
In the start time, when central device 200 was called out fire detector 10, central means 200 sent the control signal of beginning current-carrying indication to fire detector 10.
When fire detector 10 received control signal, fire detector 10 memories were 64 li of memory elements, so that just luminous from LED 35 and 35 when fire detector 10 is called out by central means 200.From this time, fire detector 10 carries out the current-carrying indication.
Second kind of control method is to reduce the amount of the light that sends from LED 35 and 35.In this case, the function that central means 200 is fulfiled, be provided with and registration need to reduce the light that sends from LED 35 and 35 amount that fire detector the address and in order to execution time of the amount that reduces the light that sends from LED 35 and 35.
At preset time, central means 200 sends the control signal of the amount that reduces the light that sends from LED 35 and 35 to the fire detector having set and registered 10.
When fire detector 10 received control signal, fire detector 10 memory was 64 li of memory elements, sent from LED 35 and 35 when being called out by central means 200 with convenient fire detector 10 and measured few light than usual.From this time, when central device 200 was called out fire detector 10, fire detector 10 sent the few light of light quantity than usual from LED35 and 35.
When central device 200 schedule time was in the morning called out fire detector 10, central means 200 sent a control signal that allows it send the light of usual amount to fire detector 10.
When fire detector 10 received control signal, fire detector 10 memories so that when fire detector 10 is called out by central means 200, were sent the light of usual amount 64 li of memory elements.From this time, fire detector 10 carries out the current-carrying indication.
In this article, in order to reduce the amount of the light that sends from LED 35 and 35, can reduce its exciting current.
The third control method is to allow in LED 35 and 35 any one luminous.In this case, the responsibility that central means 200 is fulfiled is to be provided with and registration need allow the address of that the arbitrary luminous fire detector in LED 35 and 35 and its execution time.
At the fixed time, central means 200 any one luminous control signal in fire detector 10 one of the transmission that are provided with and register allow LED 35 and 35.
When fire detector 10 received control signal, fire detector 10 memory was 64 li of memory elements, and is so that when fire detector 10 is called out by central means 200, only luminous one of from LED 35 and 35.From this time, fire detector 10 is luminous by in LED 35 and 35 any one.
When central device 200 schedule time was in the morning called out fire detector 10, central means 200 sent one to fire detector 10 and allows two control signals that LED 35 is as usual luminous.
When fire detector 10 received control signal, fire detector 10 memories so that luminous by two LED 35 when fire detector 10 is called out by central means 200, were carried out the current-carrying indication 64 li of memory elements.From this time, fire detector 10 carries out the current-carrying indication.
For the control of the emission of the light of fire detector 10, not only can adopt above-mentioned the first, the second and third party's method in any one, and can adopt multiple.For example, fire detector 10 can be controlled to luminous and reduce its luminous quantity from a LED 35.
According to above-mentioned fire detector 10, the light that sends from two LED 35 is guided to parts 20 by photoconduction, so that send light from the light-emitting area 22a that forms the ring-type pilot lamp.Therefore, whether can in any direction observe fire detector 10 in work.
On the annular component 22 of parts 20, be formed with the breach 23 and 23 of V-type shape at photoconduction.Therefore, can guide to annular component 22 to light from light incident portion 21 and 21 effectively.
On the lower surface 22d of annular component 22, be formed with many little groove 24 and 24....Therefore, the light in the annular component 22 carry out complicated more reflection and repeat this reflection, therefore, and the light grow that sends from reflective surface 22a.Consequently, can provide a kind of discernible pilot lamp with enough brightness.
Photoconduction is put into shell 30 and lid 11 to parts 20.Therefore, annular component 22 is surrounded by first reflective surface 40 on the shell 30, second reflective surface 41 on the shell 30 and the 3rd reflective surface 11d that covers on 11.Therefore, the light that sends from the remaining surface except reflective surface 22a is launched at first to the 3rd reflective surface, so that return the inside of annular component 22.Therefore, can be only luminous effectively from reflective surface 22a, thus a kind of pilot lamp that can observe easily is provided.The result is, when the layout of internals is the same with traditional fire detector, can provide a kind of pilot lamp with enough brightness, so as from around the duty of any one direction viewing lamp.
Light-emitting area 22a as pilot lamp is towards the side of fire detector 10 and the dip plane of lower surface inclination.Therefore, when being installed on the ceiling,, under fire detector and tiltedly, can both see pilot lamp to fire detector 10 for people on every side.The result is whether to be easy to observe fire detector more in work.
In the above-described embodiments, though photoconduction is with material that can printing opacity to parts 20,, photoconduction also can be made of the transparent material that contains astigmatic particle to parts 20.
As main effect, above-mentioned fire detector 10 of the present invention has high visual identification, shows to have enough brightness, can observe from any direction.Yet when the pilot lamp with fire detector 10 carried out the current-carrying indication, in the bedtime at night, it brought anxiety may for the people in the room, perhaps allows the people fall asleep.
Yet, according to fire detector 10,, can stop from LED 35 and 35 luminously by adjusting central means 200, can reduce the amount of the light that sends from LED 35 and 35, can be by only allowing a LED 35 luminous brightness that reduce pilot lamp.Therefore, can control the current-carrying indication of pilot lamp, thus make its night h.d. be in proper states.
The groove that forms with the form of superfine wire on parts 20 at photoconduction is not limited to be formed on the lower surface of annular component 22.As required, these grooves can be formed on lower surface, upper surface, inside surface or the reflective surface of annular component 22.
The groove that forms with the form of superfine wire is not limited to form by the pattern shown in Fig. 6 C.Can be made into the outside that can be transmitted into light it effectively to these grooves.For example, these grooves can form by the following pattern shown in Figure 8 that will describe.
Fig. 8 shows the photoconduction of the present invention's employing another embodiment to parts.Just as on parts 20, forming breach 23 and 23, also on parts 100, form breach 101 and 101 at photoconduction at photoconduction.Form many grooves 102,102 and 102... in photoconduction form with superfine wire on the surface of parts 100, their the crossing one another of the many grooves 24,24 that form on parts 20 than photoconduction and 24... that cross one another is more frequent.
Photoconduction is not limited to have the groove of the foregoing description to the light guiding section of parts.Photoconduction can have projection shown in Figure 9 to the light guiding section of parts.
Fig. 9 only shows as photoconduction of the present invention to the photoconduction of another embodiment of the parts part to parts 70.That is to say, as shown in Figure 9,, formed the projection 71 of a mountain peak shape in the light incident portion (not shown) of photoconduction to parts 70.Therefore, the light from the light incident portion is reflected by the dip plane of projection 71.
Shown in Fig. 4 B, photoconduction is made into tabular surface to the end of the light incident portion 21 of parts 20.Yet the end of light incident portion is not limited to this shape of the present invention.
For example, such shape can be made in the end of light incident portion 21, that is: as convex lens or concavees lens.
Figure 10 A and Figure 10 B are used for illustrating the view of photoconduction to the different shape of the end of the light incident portion of parts.
Figure 10 A shows the situation of the end of light incident portion being made the shape of convex lens.When the shape the end of light incident portion made as convex lens or concavees lens, the light that enters the end of light incident portion from light source can change over directional light.In addition, can also control the loss amount of the light on the light incident portion as far as possible.
In addition, Figure 10 B shows the situation that the end of light incident portion is made into the shape that diminishes gradually towards the direction of propagation of light from the end of light incident portion.When the end of light incident portion being made into from the end of light incident portion, can assemble the light that comes from light source towards shape that the direction of propagation of light diminishes gradually.In addition, can also propagate effectively from the next light of light source.In Figure 10 B, though the shape of end has the surface of convex lens,, concavees lens surface or plane also can be made in end.
Photoconduction is not limited to the foregoing description to the shape of parts 20.
Figure 11 A, 11B and 11C show photoconduction of the present invention another embodiment to parts.Figure 11 A is as the photoconduction of another embodiment skeleton view to parts.Figure 11 B is the side view of the photoconduction shown in Figure 11 A to parts.Figure 11 C is the synoptic diagram of the spread state of expression light.
Shown in Figure 11 A and Figure 11 B, photoconduction is also made with transparent material to parts 20 as photoconduction to parts 80.In addition, photoconduction to parts 80 by light incident portion 81 and 81 and annular component 82 form.Be formed on the annular component 82 in order to light is transmitted into outside light-emitting area 84.Be formed with the breach 83 and 83 of V word shape respectively on the top of light incident portion 81 and 81.In addition, as required, can on parts 80, make groove or projection at photoconduction with the form of superfine wire.
Shown in Figure 11 B, photoconduction is the thickest to the position that the annular component 82 of parts 80 can be made into above light incident portion 81 and 81.In addition, the distance of leaving light incident portion 81 and 81 is far away more, and the thickness of annular component 82 is thin more.
Shown in Figure 11 C, enter photoconduction and reflected by the dip plane of breach 83, so that propagate annular component 82 to the light of the light incident portion 81 of parts 80.Propagate attenuation gradually the light of annular component 82, according to the catoptrical position on the breach 83, be reflected at the diverse location place of the upper surface that is made into the dip plane of annular component 82.So each light is along different propagated.Therefore, light spreads all over the inside of annular component 82 along each direction of propagation, so that light propagates into annular component 82 everywhere effectively.Therefore, the light that sends from light-emitting area 84 strengthens, and has improved its visual identification.
Photoconduction is not limited to the foregoing description to the shape of parts.
For example, photoconduction can have a light incident portion or several light incident portion to parts.
Constitute pilot lamp, needn't just be exactly circular in order to the light-emitting area of the outside that light is transmitted into it from annular component, and can be star with many sweeps or colored and so on shape.
In addition, photoconduction is not limited to above-mentioned annular to the light-emitting area of parts.Photoconduction can be made into plate-like such as discoid to the light-emitting area of parts, perhaps is regular polygon, perhaps analogous shape substantially.Photoconduction can be made into such shape to the light-emitting area of parts, when being installed on the ceiling, in any direction can both be clear that pilot lamp to fire detector that is:.
In addition, pilot lamp of the present invention can be not only only by forming to the part of parts as photoconduction, and form by several parts.
In the above-described embodiment, though first to the 3rd reflective surface of shell 30 and lid 11 plays reflective surface, the invention is not restricted to this.
As reflecting component, photoconduction can use the material of Chinese white, metal forming, metallic paint and so on to cover to the surface except light-emitting area of parts.
In the superincumbent description, though the function that central means 200 is fulfiled is to be provided with and the registration fire detector, so that the luminance of control pilot lamp and its execution time,, self also can fulfil this function each fire detector.
In addition,, can be arranged in fire detector and always stop luminously under the situation that the execution time is not set, perhaps reduce the amount of light by pilot lamp according to the installation site of fire detector.
Second embodiment:
Figure 12 A, Figure 12 B, Figure 12 C and Figure 13 show a kind of improvement embodiment of the foregoing description.
Figure 12 A is the planimetric map of another embodiment of fire detector of the present invention.Figure 12 B is the side view of the fire detector shown in Figure 12 A.Figure 12 C is the side view of the lid of the fire detector shown in Figure 12 A.Figure 13 is the cut-open view along the intercepting of the B-B line shown in Figure 12 A of fire detector.
According to Figure 12 A, Figure 12 B, Figure 12 C and Figure 13, reference number 50 a kind of heat of representative and smoke composite type fire detectors.In addition, reference number 51 representative lids, reference number 52 is represented circuit board, and reference number 53 is represented hot-probing element (it is a thermistor or like), and reference number 54 is represented cigarette sensing chamber.Be endowed identical reference number with the identical other parts of previous embodiment.Omitted relevant light-emitting component with and the detailed description of the element of formation on the circuit board 52 of Figure 13 etc.
Fire detector 50 is a kind of heat and cigarette multiple sensor.
As shown in figure 13, hot detecting element 53 is arranged in the central authorities of cigarette sensing chamber 54.When fire detector 50 not only detected heat but also detects cigarette, fire detector 50 can be judged and catches fire.
The outside of fire detector 50 comprises base 31, shell 30, photoconduction is to parts 20 and cover 51.
Rear side at lid 51 is formed with four engaging claw 51a, the 3rd reflective surface 51d etc. as lid 11.On lid 51, be formed with ventilation blade (air fin) 56 and 56..., in order to the guiding ambient air.Center at lid 51 is formed with an element holding portion 55, and a hole is arranged on this part, and this hole communicates facing to hot detecting element 53 and with atmosphere.
The base 31 of fire detector 50, shell 30 and photoconduction are identical members to parts 20 and fire detector 10.Have only that to cover 51 are different members with fire detector 10.
It is that we are undesirable that the sniffer of fire detector has specific direction.Therefore, no matter which kind of fire detector, all should be installed in middle position as the detecting sensor of photodetector or hot detecting element.Therefore,, must change the shape of lid one by one, so that hide middle body for dissimilar fire detectors.In other words, except in order to the lid that hides middle body, needn't change parts.
According to fire detector 10 and fire detector 50, play the light-emitting area of pilot lamp effect-for example, light-emitting area 22a separately and 84-be made into ring-type.The result is only by the lid of the conversion fire detector corresponding with the method for detection of fires, just can form housing by enough standard members except that lid.
Therefore, no matter the type of fire detector how, can both be formed and dissimilar fire detector corresponding shell with standard member or the like.The result is, can produce have simpler production process, fire detector cheaply.
The Japanese patent application of submitting on April 28th, 1999 is flat-whole descriptions of 11-122757 and the Japanese patent application 2000-16138 that submitted on January 25th, 2000-comprise instructions, claims accompanying drawing and summary of the invention-do as a whole incorporated by reference by this paper.
According to the present invention, below some effects will be described.
Because the indicator lamp of fire detector is to form by the reservation shape that does not have specific direction. Therefore, Recognize easily the duty of indicator lamp, in any direction whether viewing lamp is in work.
Because indicator lamp forms by ring-type, therefore, only changes to hide the housing of fire detector The lid at top, just can be applicable to easily various types of fire detectors. The result is to reduce The production cost of fire detector.
The light that photoconduction sends light source to parts guides to the indicator lamp with reservation shape, to form indicator lamp. Therefore, whether can in any direction observe fire detector in work. In addition, can also look like traditional fire Fire detector is arranged inner components like that. The result is to realize ideally fire detector of the present invention.
Photoconduction comprises several light incident portion to parts, therefore, is directed to photoconduction to the light everywhere of parts Quantitative change big. Therefore, the brightness of indicator lamp increases. The result is to be clear that indicator lamp.
The light incident portion is extended from the light radiating portion to light source. Therefore, can be the top of light incident portion Section is positioned near the light source.
When being surface mounted to light source on the circuit board, needn't be again with lead or similar means with light source and circuit Plate links to each other. Therefore, can reduce the quantity of the quantity of parts or the assembling procedure when reduce producing it. The result is to reduce its production cost.
When lenticular was made in the end of light incident portion, the light that enters the light incident portion from light source passed through light Having made lentiform end of incident portion and become and be close to parallel light. Therefore, can be with the loss of light Be controlled at minimum.
When the end of light incident portion is manufactured the shape that diminishes gradually, enter the light incident portion from light source Light gather to the direction of propagation of light by the end of light incident portion. Therefore, can draw more light Lead the light radiating portion.
The light that enters the light incident portion from light source is guided by light guiding section, in order to propagate the light radiating portion. Therefore, can effectively propagate light into the light radiating portion.
When the breach that plays light guiding section had the V-arrangement shape, moulding was this with V-arrangement shape easily The breach of shape. Therefore, can form easily light guiding section.
At least a portion of residual surface in the surface that consists of the light radiating portion except light-emitting area is with anti-When light spare hid, the light that sends from the surface except light-emitting area can be sent out because the reflecting component reflection turns back to light Penetrate the inside of part. Therefore, can be effectively only luminous from light-emitting area. The result is that a kind of energy is provided The indicator lamp that enough is clear that.
When reflecting component is housing a part of, only just can be enough reflective by photoconduction is put into housing to parts Part covers the light radiating portion. Therefore, can realize easily the quantity of the present invention and don't increase assembling procedure.
Because photoconduction is made into to side and the lower surface of housing to the light-emitting area on the parts, therefore, when When being installed to such fire detector on the ceiling, people on every side under the fire detector and Tiltedly indicator lamp can both be seen in the below. Therefore, whether be more prone to observe fire detector in work.
The light that comes from the light radiating portion carries out because of a large amount of microflutes or the dimpling that the light radiating portion forms More complicated reflection, and repeat such complex reflex. The brightness of the light that therefore, sends from light-emitting area increases By force. The result is that a kind of indicator lamp that can be more clearly visible can be provided.
The distance of leaving the light incident portion is more far away, and the density of micro-structural part is more big. Therefore, from the light emission part The quantitative change of the light that the whole light-emitting area of dividing is sent is even. The result is, when the light time of indicator lamp emission from light source, From can both clearly recognizing indicator lamp Anywhere.
Because the micro-structural that forms part is distributed in each place of light radiating portion equably, therefore, it is seen It is attractive in appearance to get on, especially when not luminous.
When the inside of light radiating portion included astigmatic particle, the light of the inside of light radiating portion loose because of these Light particle and carry out more complicated reflection, and repeat such reflection. Therefore, the light that sends from light-emitting area Quantitative change big. The result is, from can clearly recognizing indicator lamp Anywhere.
The distance of leaving the light incident portion is more far away, and the quantity of the astigmatic particle that comprises in the light radiating portion is more big. The quantitative change of the light that therefore, sends from the whole light-emitting area of light radiating portion gets evenly. The result is to work as indicator lamp When luminous, can be clear that luminous indicator lamp.
When astigmatic uniform particles be contained in the light radiating portion everywhere the time, it seems attractive in appearance, especially works as When not luminous.
That part of the close light incident portion of light radiating portion is the thickest. In addition, leave the light incident section The distance of dividing is more far away, and its thickness is more thin. So light is propagated into the light radiating portion along all directions. Therefore, Can effectively propagate into the light radiating portion to light everywhere. The result is, the light grow that sends from light-emitting area. In addition, improved the visual identification of indicator lamp from the outside.
Because can to stop indicator lamp luminous, therefore, can be as required, for example, when night, referring to Show that lamp turns off.
Because the amount of the light that sends from indicator lamp can change, so, can be as required, for example, When night, the amount of light is reduced to lower level.
Because several light sources are set and can change quantity in order to luminous light source, so, can basis Need, for example, when night, reduce the quantity of illuminating source, in order to reduce the light that sends from indicator lamp Amount.
Therefore, its main effect is high visual identification, shows: the indicating lamp of fire detector Enough brightness and can be from observing is Anywhere arranged. Yet, refer to when the indicator lamp with it carries out current-carrying When showing, in the bedtime at night, indicator lamp brings anxiety may for the people in the room, perhaps allows the people enter Sleep. But, can stop the luminous of indicator lamp or reduce the luminous quantity of indicator lamp. Therefore, night just During bedroom, can be controlled at a kind of suitable state to indicator lamp.
The middle part of shell is formed with a hole, and this hole is with covering (it is parts outside the shell) Hide. Therefore, by changing the shape of lid, can provide a kind of housing, this housing can be applicable to various The fire detector of type.
That is to say, for example, when fire detector is a kind of smooth decentralized smoke detector, can be not having The simple lid of ad hoc structure is arranged as lid. When fire detector be heat and the smog composite detector, perhaps During Bolometer, can be the lid in the space that has to hold hot detecting element as lid.
Therefore, only by changing the lid of housing, just can change seriatim the Shell-Class of fire detector Type. The result is, for various types of fire detectors, and Design and manufacture housing one by one, from And can reduce its production cost.
Particularly, fire detector also has an indicator lamp of making ring-type. Therefore, in any direction can both Enough clearly viewing lamps. The result is, can provide a kind of have good visual identification, produce Cost is low, colory fire detector.
